1. Description of circuit
This troubleshooting code is used to
identify the possible internal faults of
EBCM.

2. Conditions for setup of
troubleshooting codes
DTC C0055 will be set up when there is
possible fault of internal
component/microprocessor.

3. Actions to be taken for setup of
troubleshooting codes
(1) The electromagnetic relay is turned off
and pump motor and solenoid are
disconnected with the power source. ABS
and DDRP are both disabled;
(2) Save DTC C0055;
(3) ABS is disabled and ABS alarm lamp
is on.

4. Conditions for clearing
troubleshooting codes
(1) If the conditions for setting up
troubleshooting code DTC C0055 are gone,
corresponding scanning tools can be used
to clear the troubleshooting code.
(2) If the troubleshooting code does not
appear for 100 driving cycles running, it
can be eliminated from the database.

5. Assistance to troubleshooting
(1) When C0055 is displayed on the
scanning device, it shall be followed with
two digits (XX). They shall be recorded
along with the other OTC displayed.
(2) Before making an analysis of C0055,
please repair the troubles concerning low
voltage and driving performance or other
electrical troubles.
(3) The connection between the EBCM
and BPMV shall be reliable, fast and free
of corrosion, leakage and/or damage.

To solenoid valve

From solenoid valve

This troubleshooting code is used to
identify the possible internal faults of
EBCM. When the EBCM relays are
started (turned on), voltage is provided to
the valve solenoid and pump motor.

2. Conditions for setup of
troubleshooting codes
DTC C0056 is set up when there is
internal fault.

3. Actions to be taken for setup of
troubleshooting codes
(1) ABS alarm lamp is off;
(2) Save DTC C0056;
(3) ABS is enabled.

4. Conditions for clearing
troubleshooting codes

(1) If the conditions for setting up
troubleshooting code DTC C0056 are gone,
corresponding scanning tools can be used
to clear the troubleshooting code.
(2) If the troubleshooting code does not
appear for 100 driving cycles running, it
can be eliminated from the database.

5. Assistance to troubleshooting
(1) Before making an analysis of C0056,
please repair the troubles concerning low
voltage and driving performance or other
electrical troubles.
(2) The connection between the EBCM
and BPMV shall be reliable, fast and free
of corrosion, leakage and/or damage.
(3) DTC C006 is set possibly due to
troubles of the EBCM relays.

Power supply

System relay

1. Description of circuit
Application and release of solenoid is an
inalienable part of EBCM. When the car is
ignited, the storage battery provides power
to the solenoid so that the solenoid relay is
turned on. The EBCM controls the
solenoid valve through the grounding of
relevant coil circuit.

2. Conditions for setup of
troubleshooting codes
Corresponding troubleshooting codes will
be set up when the EBCM detects any
ground fault or solenoid valve short circuit
to the power source.

3. Actions to be taken for setup of
troubleshooting codes
(1) The electromagnetic relay is turned off
and pump motor and solenoid are
disconnected with the power source.
(2) Save the various DTC;
(3) ABS is disabled and ABS alarm lamp
is on.
(4) DDRP is disabled and braking alarm
lamp is on (only applicable to C0065 and
C0067).

4. Conditions for clearing
troubleshooting codes

troubleshooting code DTC C0061 through
C0068 are gone, corresponding scanning
